JOINT FOR BRACELETS.

Specification of Letters Patent.

Patented Oct. 22, 1907.

Application filed June 21, 1907. Serial No. 380,047.

To all whom it may concern:

Be it known that I, NILS G. WALLENTHIN, a citizen of the United States,residing at Attleboro, in the county of Bristol and State ofMassachusetts, have invented certain new and useful Improvements inJoints for Bracelets, of which the following is a specification,reference being, had therein to the accompanying drawing.

This invention relates to joints for bracelets, and has for its objectto provide a strong and durable joint of simple and practicalconstruction.

A further object of the invention is to provide a joint which will beneat in its appearance when the bracelet is open and will be in suchform as to entirely close the gap or opening between the arms of thebracelet when the same are drawn apart.

I-Ieretofore in joints of this construction one of the members have beenusually provided with a forked end which forked portions were liable tobe opened or sprung apart when subjected to a heavy lateral strain. Toobviate this difficulty I have provided a cross bar or tie at the end ofthe said portions whereby the same are firmly tied tpgether to supporteach other thereby greatly increasing the strength of the joint.

Another feature of this device is that the two members are joinedtogether by means of a stud riveted in position, said stud beingprovided with a T-shaped head whereby the members are inseparably boundto gether and at the same time allowed to slide freely one upon theother.

The invention is fully set forth in this specification and moreparticularly pointed out in the appended claims.

In the accompanying drawings: Figure 1 shows the bracelet in its closedposition with a portion broken away disclosing the joint. Fig. 2 is anenlarged sectional side elevation of the joint members inserted in theadjacent ends of the tubular arms, said joint being in its openposition. Fig. 3 is an enlarged plan view showing the under or outerside of the slotted joint member. Fig. 4- represents a correspondingside of the opposite or lougue member. Fig. 5 is a side elevation of theslot member. Fig. 6- is a corresponding elevation of the tongue member.Fig. 7- is the retaining stud having a T-shaped head.

Referring to the drawings at 11 are the two side arms of the braceletpreferably constructed of tubing and bent into the form to fit looselyaround the wrist or arm of the wearer. In bracelets of the characterillustrated it is customary to divide the same into two parts or armsand binge said arms together so that they may be separated or opened toallow the wrist of the wearer to pass therethrough after which the armsmay be closed together and locked in any convenient way. The point ofseparation at 2 is where the bracelet joint is formed whilediametrically opposite at 3 is the opening point where the two parts arebrought together and secured by any suitable locking device.

My improved bracelet joint is constructed of two interlocking memberswhich may be formed integral with the adjacent ends of the braceletarms, if desired, or they may be constructed separate and independent ofsaid arms and subsequently secured in the tubing. At 4 is shown one ofthe interlocking members namely the tongue member, that is preferablyconstructed of solid wire bent to form the shape of the tubing andadapted to fit and be fixed into one end of one of the arms. Theopposite member 5 may also be constructed of solid material, if desired,and is also bent to take the contour or form of the tubing and isadapted to be fixed into the adjacent end of the opposite arm. Themember 5 is provided at one end with a slotted portion 6 formedlengthwise therein, the outer ends being connected by the bridge piece 7which is preferably formed integral with said fingers 8 and 9 to stiffenand support the same. These fingers are formed on their upper face at 10on the arc of a circle, the underside of the same at 11 being concavedalso 011 a circle concentric with the upper face 10.

The bridge piece 7 is cut away at 12 so as to fit over the correspondingtongue on the opposite member. The tongue member 4 is provided with aforwardly extending overhanging bearing portion 13, which portion isformed integral with said member. The upper surface of the outer end ofthis portion is rounded off at 14 on the swinging radius of the joint soas to work into and just clear the tubing as the bracelet is opened andclosed, as best illustrated in Fig. 2. The underside of this bearingportion at 1414 is also formed on the arc of a circle to correspond withand slide on the circular faces ]0-10 oi the fingers 8 and 9 of themember 5. Extending downwardly from the central portion of this bearingmember is a narrow guiding tongue 15 which is adapted to engage therecess 6 in the opposite member and slide between the fingers 8 and 9. Asmall hole 16 is drilled through the tongue and substantially in thecenter of the extending portion for the reception of the retainingstud.' This retaining stud 17 is preferably constructed with a T- head18 that extends across to engage both fingers, a body portion 19, anda"short shank 20, which shank is adapted to fit in the hole 16 in thetongue member. After the parts have all been thus formed the two jointportions of the members are placed in position one upon the other andthe shank 20 of the retaining stud is forced into the hole 16 in thetongue member and riveted therein, firmly retaining the two memberstogether at the same time affording an easy sliding movement of one uponthe other. The members may then be secured in the adjacent ends of thetubular arms and the bracelet is complete.

By constructing a bracelet in my improved manner the same is exceedinglystrong and durable, the fingers being firmly tied together at their endsand adapted to engage the guiding tongue in the opposite member whichslides between them. The two members are then subsequently iastenedtogether by the retaining stud 17 which also serves as a stop to limitthe opening motion of the bracelet by the bringing up of the bridgeagainst the body of the stud, in the manner illustrated in Fig. 2.

My improved joint is very simple and inexpensive in construction, isexceedingly strong and durable and effective in its operation.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent, is:-

1. In a bracelet, a joint formed of two members hinged together, one ofsaid members being provided with a reduced portion having an elongatedslot forming a pair of outwardly extending fingers, a bridge across theouter ends of said fingers to tie the same together. the extending;portion of the opposite hinged member being adapted to slide on saidfingers, and a retaining stud for holding the members together.

2. In a bracelet, a joint formed 01' two members hinged together, one ofsaid members being provided with a reduced portion having an elongatedslot forming a pair of outwardly extending fingers, a bridge across theouter ends of said fingers to tie the same together, said fingers beingformed on both their upper and under faces longitudinally on the arc ofa circle, the extending portion of the opposite tongue member beingcurved to fit and slide on said fingers, and a retaining stud forholding the members together.

Hi. In a bracelet, a joint formed of two members hinged together, one ofsaid members being provided with a re duced portion having an elongatedslot forming a pair of outwardly extending fingers, a bridge across theouter ends of said lingers to tie the same together, said fingers beingformed on both their upper and under faces longitudinally on the are ofa circle, the extending portion of the tongue member being curved to litand slide on said lingers, and a stud adapted to pass through said slotand be riveted in said tongue member, said stud being provided with ahead adapted to cross said slot and engage the outer curved surface ofboth fingers, said stud being also adapted to vengage the bridge andform a stop to limit the opening motion of the bracelet.

In testimony whereof I aifix my signature in presence of two witnesses.
